The answer is 8x^6y^12.

Explanation:

((2xy^2*(-2x^0 y^2))/(-2x^-1 y^0))^3

First, remember that anything raised to the 0th power is equal to 1. So start by canceling out all the terms that are raised to 0.

((2xy^2 * (-2(1)y^2))/(-2x^-1(1)))^3

((2xy^2 * (-2y^2))/(-2x^-1))^3

Multiply the numerator by adding the exponent of like terms. Don't forget the negative sign!

((-4xy^4)/(-2x^-1))^3

((2xy^4)/(x^-1))^3

Remember that anything raised to the -1 is basically a reciprocal, so:

x^-1 = 1/x

Therefore:

((2xy^4)/(1/x))^3

which is

(2xy^4 * x)^3

(2x^2y^4)^3

Distribute the exponent

2^3 * x^(2 * 3) * y^ (4*3)

= 8x^6y^12
